D2 scratches?

Tools.. Not jewels!! If ya use it, you will get a few more.. John

 

I have more than a few knives in D2.. Never had an issue so far.. Now I don't mean to say that some cant pop up but that can happen to any steel.. I don't believe/read/pay attention to any internet hype on most things.. Use it and enjoy.. If an issue pops up later I am sure it can be corrected.. John

 

D2 is fairly decent in the wear and tear resistance dept, but it will scratch if it makes contact with an abrasive surface. I have seen a Benchmade 710 scratched so bad it looked like someone wiped it down with sandpaper.

 

From your pics, it looks like regular ol' scratches to me. That tree stump is full of dirt / abrasives.

 

D2 has been used in tools and knives for generations. Something tells me if it were really that brittle and likely to break, it would have gone the way of the dodo decades ago.

Is it possible there is some sand, or pebbles, or other gritty stuff on the surface of that wood? It might be a silicate scratching the blade rather than the wood itself.

 

yeah, it scratches because silica particles (silicon) tends to be everywhere, even in trees. The only way to minimize scratches is if your blade hardness is up around 65+...

there are a few threads here about it (if i find it I'll link it here)...
also somewhat common is quartz, which unfortunately has mohs hardness of 7... to avoid scratching those you might need @Ban to make you something out of zdp-189 or something crazy

 

Most of the things you hear about knife steels on Internet knife forums, outside of the occasional outright falsehood, can probably be summed up like this: "true only when considered as a relative thing compared to some superior option, and generally mattering very little in actual use".

 

Something else to consider, your blade may have came in contact with small steel fragments that chipped of the chainsaw chain when cutting the tree down.

 

I have a chopper in d2 that I use for limbing trees. Holds an edge very well and I've only experienced chipping when hitting rocks, and they were minor. I think it's at 61-62 RC.

 

Can i ask what blade that is?

thanks.

 

Charlie Mike here on the forums made it.

 

If you do a search there was a recent thread on Kizlyar Supreme being very bad knives. It's probably not d2 and probably not a good heat treatment.

 

Sick knife. I want one.

 

it might be because some Chinese mfgs use this 'type' of d2 - http://www.zknives.com/knives/steels/EST/ytl122.shtml

which isn't really d2, since it has around 0.2% vanadium instead of 1%, and the other variances are rather loose at best...
I hope the better Chinese makers don't touch this stuff

 

Whereas Kizlyar [not Kizlyar Supreme] make rather good knives in my experience.
